Some experts say that handing over technology has effectively become a cost of doing business in China — a market too big for most companies to ignore.

“Many Chinese companies go after technology hard and the tactics they use show up again and again, leading us to believe there is some force (the government?) teaching them how to do these things,” said Dan Harris, a Seattle-based attorney who advises international companies on doing business in China.

“The thing is that the foreign companies that give up their technology usually do so at least somewhat of their own volition,” he told CNNMoney. “Yes, maybe they need to do so to get into China, but they also have the choice not to go into China, right?”
